Utilities Mapping
Imagine how useful it would be to know exactly what lies beneath your feet before starting excavations, to know for sure where expensive fiber-optics cut across your site or how deep utility pipes lie.
The savings in both time and money that can be made by using sub-surface scanning cannot be over-estimated. As a result these services are rapidly becoming indispensible to many of our clients.
Why use Utilities Mapping?
Non-intrusive mapping provides you with an AutoCAD drawing of the surveyed area clearly showing all manner of obstacles (utilities, voids, foundations etc), their depth, position and type. All this can be done without disturbing the ground and with minimal disruption to the public or other site workers. Crucially, the survey may well show elements that were not shown on any stats – simply showing their presence will allow you to plan your works accordingly, saving time, money and improving safety in the process.
What can we do?
Underground services surveys are frequently carried out using Radiodetection CAT & Genny equipment. Drainage runs can be traced using a sonde transmitter on a reel which is fed from the surface and along the pipe runs. The transmitted signal is traced from above ground using a detector.
While cover, invert levels and pipe sizes can be provided, we are also able to trace other below-ground services (e.g. cables, metal pipes etc) and provide relevant depth information. Where certain obstacles cannot be detected by the CAT our engineers use a more sophisticated Ground Penetrating Radar (GPR). Where even greater levels of accuracy are required City Surveys can deliver a practically unique Vacuum Excavation service.
Key benefits of Sub-Surface Scanning?
- Reduced levels of cost, delay and risk
- Improved levels of safety
- Unnecessary excavation kept to a minimum
- Disruption to road/other site users severely reduced
- Highly accurate data provided
